This disclosure provides a multi-channel testing device and method for a digital instrumentation and control system of a nuclear power plant. The multi-channel testing device includes: a load simulation module comprising a fixed resistor and an adjustable resistor; the adjustable resistor receives a first control signal from a host computer and adjusts its resistance value according to the first control signal; the fixed resistor and the adjusted adjustable resistor together constitute the target load of the device under test; an analog signal acquisition module acquires the voltage across the fixed resistor and transmits the voltage to the host computer; the host computer calculates the current signal of the circuit under test formed by the device under test and the load simulation module based on the voltage across the fixed resistor and the actual resistance value of the fixed resistor; and analyzes whether the device under test passes the test based on the sampled waveform of the current signal; both the load simulation module and the analog signal acquisition module are located inside the chassis; this solves the problem of large size of traditional testing instruments and realizes simultaneous testing of multiple devices under test, improving testing efficiency.

A synchronization system for synchronization of at least one physical element and at least one digital element of an analog / digital instrument of a vehicle is described, which envisages: a first driving sub-system, for driving the digital element and including a first digital processing unit operatively coupled to the digital element; a second driving sub-system, for driving the physical element and including a second digital processing unit operatively coupled to the physical element. The first and second digital processing units of the first and second driving sub-systems implement a synchronization algorithm to determine a synchronism between an operation of the first driving sub-system and a corresponding operation of the second driving sub-system, said synchronization algorithm including operations that are independent of the use of a common reference clock and are based on a set of predefined signals exchanged between the first and second digital processing units.
